Abstract: An electrochemical cell for use in gas detection includes a cell body having an electrolyte cavity and a separate sensor cavity. The sensor cavity holds stacked sensor elements including a counter electrode, electrolyte mat, reference electrode and sensing electrode. A wick draws the electrolyte from the electrolyte cavity to the electrolyte mat. The sensing electrode closes off the sensor cavity and seals the counter and reference electrodes therein. The only gas which contacts the counter and reference electrodes is that which passes through the sensing electrode or is generated by the counter electrode and becomes dissolved in the electrolyte.

Abstract: Dispersions of hydrophobic substance eg resin emulsions, usually having a relatively low average particle size can be continuously and speedily prepared by feed a hydrophobic substance in the liquid state into at least two static mixers, arranged in a series. The resin is introduced at a temperature above 50 degrees C but below its degradation temperature of hydrophobic substance and water under pressure is introduced into the first mixer. The mixture of resin and water is passed to another mixer maintained at a temperature lower than that prevailing in the first mixer and below the boiling point of water. Optionally aqueous solution of surfactant under pressure instead of water is introduced into the first mixer and optionally aqueous surfactant is introduced into the second mixer.

Abstract: This invention relates to a process for preparing a supported metallocene alumoxane catalyst for use in the slurry, gas or liquid phase polymerization of olefins. The invention particularly relates to the use of silica gel containing from about 10 to about 50 per cent by weight adsorbed water as the catalyst support material. It has been found that such silica gel may be safely added to an aluminum trialkyl solution to form by direct reaction with the adsorbed water content of the silica gel catalyst support material the alumoxane component of the catalyst system. An alumoxane coated silica gel is formed to which a metallocene may be added. The resulting material can either be used in this slurry state for slurry polymerization or can be used for liquid phase polymerization of olefins.

Abstract: A ventilation box for a masonry wall has mutually separated ducts for incoming air and outgoing air, each of which can be closed by means of a nonreturn flap, namely an incoming air flap and an outgoing air flap. Incoming air flap and outgoing air flap are pivotably mounted separately and independently of one another, but connected to the outgoing air flap is a locking member which, in the closed position of the outgoing air flap, projects into the pivot path of the incoming air flap and locks the latter in the closed position and, on opening of the outgoing air flap, releases the incoming air flap for the opening movement. The locking element can at the same time be designed as a compensating weight for the outgoing air flap. <IMAGE>

Abstract: An apparatus 10 controls the enable response time of a laser diode 12 during the reception of a data signal. The laser diode 12 is powered by the combined outputs from a pulse and bias current supply 14, 16. The pulse current supply 14 is connected to an external controller (not shown), which provides serial pulses of data. The pulse current supply 14 converts the serial pulses of data to a series of current pulses that drive the laser diode 12 between high and low optical output intensity. The bias current supply 16 provides a DC offset to the pulse output of the pulse current supply 14. Further, the apparatus 10 controls the level of the DC offset to maintain the minimum optical output intensity of the laser diode 12 at a preselected desired level. The apparatus 10 constitutes a closed-loop, bias-current-supply controller 20, which employs a feedback path for monitoring the optical output intensity of the laser diode 12 and controlling the optical output intensity to a preselected value. To accomplish stable operation but permit rapid response to an enable signal, the closed-loop, bias-current-supply controller 20 has a first preselected response characteristic for a first preselected period of time in response to receiving the enable signal and a second preselected response characteristic thereafter.

Abstract: The method according to the invention is used for automatic identification of communications terminal addresses (kea) in bridges (NUE) connecting two local area networks. With the aid of a hash method, hash memory addresses (hsa) are calculated from the communications terminal addresses (kea) inserted in the messages packets (pi) which are transferred via the local area networks (LBN, LRN), which hash addresses in each case represent the address of a memory space of a hash storage device (HLB, HVB). Address information (ai) is recorded in the addressed memory space, indicating a memory area (SB) in an address table storage device (LBSP, VBSP). With the aid of validity information (gi), this memory area (SB) is checked for the presence of a communications terminal address (kea). If the same communications terminal address (kea) is already recorded, the detected communications terminal address (kea) is evaluated as identified. If the communications terminal address (kea) is not present, the currently detected address is recorded in the addressed memory space (SB). <IMAGE>

Abstract: Large format TV tubes must produce a high peak brightness in order to be acceptable to the user. This results in a large beam current in bright areas of the picture and in a subsequent defocusing of the resulting spot on the display and in a loss of the sharpness of vertical and horizontal transitions. The apparent sharpness of a vertical transition is gained by modifying the deflection of the TV receiver such that, at vertical transitions, the line on the bright side of the transition is deflected away from the transition region. Advantageously, the amount of vertical scan modulation corresponds to a multi-level control signal and depends on the grey levels of the transition.
